Crate tabled

This library provides an interface to pretty print vectors of structs

Get started

The common and probably the best way to begin is to annotate your type with #[derive(Tabled)]. You can also implement it on your own as well.

There's an example. Precisely it can be printed and you will see the content of expected variable as an output.

use tabled::{Tabled, table};

#[derive(Tabled)]
struct Language {
    name: String,
    designed_by: String,
    invented_year: usize,
}

let languages = vec![
    Language{
        name: "C".to_owned(),
        designed_by: "Dennis Ritchie".to_owned(),
        invented_year: 1972
    },
    Language{
        name: "Rust".to_owned(),
        designed_by: "Graydon Hoare".to_owned(),
        invented_year: 2010},
];

let table = table(&languages);
let expected = "+------+----------------+---------------+\n\
                | name |  designed_by   | invented_year |\n\
                +------+----------------+---------------+\n\
                |  C   | Dennis Ritchie |     1972      |\n\
                +------+----------------+---------------+\n\
                | Rust | Graydon Hoare  |     2010      |\n\
                +------+----------------+---------------+\n";

assert_eq!(expected, table);

It should have a clue in what why print the field accordingly each field should implement std::fmt::Display The example below is not compiled

#[derive(Tabled)]
struct SomeType {
    field1: SomeOtherType,
}
 
struct SomeOtherType;

This crate implement the trait for default types. Therefore you can use this to print one column vectors

use tabled::{Tabled, table};

let some_numbers = [1, 2, 3];
let table = table(&some_numbers);
